According to the AHD entry on barbican http://www.bartleby.com/61/18/B0071800.html, there was an intermediate step in Mediaeval Latin between the French and Persian. Are there any more missing steps? What contact was there between Latin speakers and Persians at the time when barbicans were being built? Shouldn't it have come through Byzantine Greek or through Arabic?
